1. Does ‘start’ mean the same as ‘begin’ in English?
  2. My new car is the same model as my old one.
  3. Tom’s house is the same size as mine.
  4. You have the same pen as I have.

In sentence one to three, "as" is a preposition and in sentence 4, "as" is a conjunction. Am I right?

1 Answer 1


Yes. In the first three sentences, "as" is followed by a noun phrase, so it is a preposition.

In the fourth sentence, "as" is followed by a complete clause, so it is a conjunction.

Also, it's worth noting that "as" can be an adverb, when followed by an adjective, adverb, or comparative such as "much" or "many."
